What term describes the process of removing decay from a tooth before filling?

• A. Cavity preparation
• B. Tooth restoration
• C. Decay extraction
• D. Restorative removal

Answer: (A)

Cavity preparation is the correct term that describes the process of removing decay from a tooth before filling. During cavity preparation, the dentist carefully removes any decayed tissue from the affected area of the tooth to ensure that all decay is eliminated and that the remaining tooth structure is stable and intact. This process is crucial for the long-term success of the filling, as any remaining decay can lead to further deterioration or infection.

Proper cavity preparation involves isolating the tooth, often with a rubber dam, and using specific dental instruments to clean out the decayed area. This prepares the tooth for the restoration material that will be placed afterward, ensuring a secure bond between the filling and the tooth structure.

Other terms presented may seem relevant but do not accurately describe this specific process. Tooth restoration generally refers to the entire procedure of correcting a tooth's structure, including placement of the filling but not limited to just the decay removal aspect. Decay extraction implies the removal of decay but does not encompass the preparatory steps needed to prepare the tooth for a filling. Restorative removal sounds like it could pertain to the procedure but is not a recognized term in dental practice, making it unclear and less specific than cavity preparation.
